Removing and inspecting spark plugs tell you a lot about how well the engine is running and what may be causing problems. All spark plugs should be removed and checked every 30,000 miles - even if your BMW is low maintenance - you're told to change spark plugs at 100,000 miles. This prevents the plugs from seizing in the block, causing expensive repairs down the road. Always note which plug came from which cylinder.
Why You Should Change Your Spark Plugs. Car maintenance is full of small reminders. There always seems to be something to be concerned about underneath the hood. Mechanics will warn of the need to check on the battery, change the oil, make sure the transmission fluid is not cloudy, and a lot of other little things. Spark plugs are part of the engine that need to be maintained and changed when necessary. Car owners have to appreciate that this is more than just another nagging little poke in the ribs. Spark plugs are extremely important. It can be very understandable why car owners will ignore the spark plugs.
